The Scotch-Brite™ Roloc™ gasket removal disc is ideal for removing old gasketing residue and preparing a surface for a new gasket.
3M Scotch-Brite non-woven 7711 quick change disc uses aluminum oxide as the abrasive material and has a diameter of 3 in. Since this product is non-woven, grade is generally used to describe the abrasiveness; with the 07711 having a coarse grade.

Specification parameters description:Abrasive Material: Values: A/O Aluminum Oxide AO A/Z Alumina Zirconia AZ S/C Silicon Carbide SC Alumina Zirconia Aluminum Oxide Aluminum oxide is an artificial abrasive suited for general purpose stock removal and finishing. It is the mostly commonly used abrasive and can be used for most steels and ferrous alloys. Aluminum oxide is slightly softer but tougher than silicon carbide. Ceramic Ceramic is used for aggressive cutting and grinding of stainless steel, titanium, and metal alloys. The abrasive grain is designed to fracture during use so that it maintains sharpness. Ceramic Aluminum Oxide Diamond Diamond can be either natural or manufactured and is one of the hardest abrasive materials. It is commonly used for grinding and polishing stone and very hard steels, and for sharpening other cutting tools. Felt Silicon Carbide Silicon carbide is a manufactured material that is extremely hard but brittle. It is commonly used for fast cutting under light pressure, particularly on cast iron, nonferrous metals, and materials such as glass and plastic. Zirconia Zirconium
Grade: Grade is a measurement of the size of abrasive particles embedded in coated abrasives. It is a more general measurement of the level of precision, and corresponds roughly to grit. A smaller grit number means larger particles and a coarser grade, while high number grits are used for finer work.
Quick Change Type: Quick change attachments allow discs to be switched easily while providing a more stable grip than hook and loop or PSA attachments. Quick change discs are designed to fit disc holders with one of these main types: Type I (Type P or TP) - snap on/off Type II (Type TS, TSM, or S) - female threaded twist on/off Type III (TR or R) - male threaded roll on/off TN - Disc has its own 5/8-11 inch threaded mounting nut and can be mounted directly on a tool with the proper backup accessory
